服务器端文件更改后，未定义Passport.js req.user对象（节点，快速）

Question

I'm using passport.js to authenticate the user to my app, but I have noticed that after any changes on server files, req.user is undefined. Nodemon is correctly reloading all the files but after I hit refresh - an app is broken and req.user is undefined. What is important: it only happens when server-side files are changed. When there are no changes I can refresh many times and everything works well.

This is my config code:

app.use(
  session({
    secret: process.env.EXPRESS_SESSION_KEY,
    unset: 'destroy',
    saveUninitialized: false,
    resave: false
  })
);
app.use(bodyParser.urlencoded({ extended: false, credentials: true }));
app.use(bodyParser.json());
app.use(
  cors({
    origin: FRONTEND_URL,
    credentials: true
  })
);
app.use(passport.initialize());
app.use(passport.session());
app.use(express.static('../../dist'));

I can't find any solution. It's pretty annoying to rebuild the whole app after any file change on the server side.

I can also notice that req.session is empty after file changes. Why is that?

Answer 1

You haven't specified the store property , so Express Session will default to using a MemoryStore . This keeps session data in memory, so when you change the server side code and trigger a reload of the server, the session store is wiped and all session data is lost.

Use a different session store (such as session file store ) which stores the data somewhere persistent.

Answer 2

Use below link to and see see there is some thing called Store . Use that which actually storing using passportjs sessions
